Specification of Letters Patent.

Patented Apr. 5, 1910.

Application filed May 5, 1909. Serial No. 494,022.

To all whom it may concern:

Be it known that 1, JOHN P. Tyn, a citizen of the United States, and a resident of Rochester, in the county of Haskell and State of Texas, have invented certain new and useful Improvements in Drills, of which the following is a specification.

Referring to the drawings forming a part hereof, Figure 1 is an end view of the improvement. Fig. 2 is a side View. Fig. 3 is a partial vertical transverse section. Fig. at is a section on the line 1-1 of Fig. l, and Fig. 5 is a detail View of the worm and the toothed flange showing the worm disengaged therefrom.

The present embodiment of the invention comprises a frame of substantial construction, comprising in the present instance a base 1, upon which is rotatably mounted a horizontal wheel 2, provided with a periphoral groove 3 for a purpose to be presently described, and with a plurality of lateral projecting ratchet teeth 4 on its lower face.

The wheel 2 is ring shaped as shown in Fig. 3, and a cylindrical casing 5 is arranged within the wheel, the casing being provided with upper and lower annular flanges (5 engaging above and below the wheel, and with a third flange 7 which rests upon a platform 8 forming a portion of the frame.

Above the wheel, the framework is pro vided with uprights 9, which are connected at their top by cross bars 10, 11, and one leg 12 of a tripod secured to one of the cross bars 10, by means of angular brackets 13. The other legs 1-1 of the tripod are connected with the framework by angle brackets 15, and the three legs of the tripod are connected at their top by a bracket 16. The legs 14: consist each of two sections which are connected by fish plates 17.

A reel 18 is journaled in bearings 19 on a pair of uprights 9, the trunnions 20 of the reel projecting beyond the bearings at each end. One of the trunnions is provided with a brake wheel 21, engaged by a b -ake band 22, frame as at 23, and the other connected as at 24;, with a lever 25, journaled as at 26 on a forward upright, and adapted to engage having one end secured to thej a toothed quadrant 27 whereby to retain the lever in its adjusted position.

The above mentioned trunnion is also provided outside of the brake wheel with a sprocket wheel 28, connected by a sprocket chain 29 with a sprocket wheel 30, slidable on a shaft 31, journaled in bearings 32, on the cross-bars 11.. The sprocket wheel 30 l is provided with a clutch face 33, adapted to engage with a clutch face 3 1, integral with a groove pulley 35 over which passes a cable 36, which encircles the groove 3 on the wheel 2 before mentioned, the direction of the cable being changed by idlers 37, 38 journaled on the framework. It will be understood that the sprocket wheel 30 is loose on the shaft 81, in order that it will move longitudinally thereof, to engage or disengage the sections 33, 34 of the clutch.

One flange 39 of the drum or reel 18 is provided with gear teeth as shown in Fig. 2, which are engaged by a worm 40 on a shaft 11, journaled on the frame in bearings i1 and provided at its free end with a hand wheel 42 for convenieime in manipulating the shaft. it will be evident from the description that the reel may be rotated by means of the hand wheel and worm gear, or by power from the shaft 31. Then not in use, the worm is disengaged from the gear teeth of the flange by rotating the worm l shaft in a reverse direction until the worm l is out of engagement with the flange.

\ A second reel 1?) is journaled in bearings Lt on the uprights t) above the reel 18, and parallel therewith, and the outer end of the reel shaft is provided with a sprocket wheel connected by a sprocket chain 16, with a sprocket wheel 11T loosely mounted on the shaft 31,. The sprocket wheel 46 has rigid therewith a clutch section 18, the other section 49 being secured to the shaft, and the two sections engage by friction when they are moved into contact by means to be presently described. k Each of the clutch sections 30 and 48 is l provided with an annular groove 50 in which engages the forked arms 51 of levers 52 |whcreby to manipulate said clutches in a t well understood manner. 1 It will be evident, that by moving the means for connecting and clutch sections 48, 49 into contact, the reel 43 will be driven from the shaft 31, which is moved continuously from the wheel 2, and the said wheel is adapted to be moved by a sweep 50 of ordinary construction.

The drill rope 51, passes from the drill (not shown) over a pulley 52, journaled in the tripod, thence downwardly and over a pulley 53 journaled in the one pair of arms 54 of an elbow lever pivoted as at 55 on the frame, the other arm 56 being provided with a roller 57 which engages the faces of the ratchet teeth 4 before mentioned. From the pulley 53, the rope extends to the drum or reel 18 before mentioned, and winds thereon, in passing to and from the pulley 53, the drill rope passes through the cylindrical casing 5.

It will be evident from the description that as the wheel 2 rotates in the direction of the arrow in Fig. l, the pulley 53 will be gradually depressed to raise the drill While the friction roll 57 is in engagement with the inclined face 58 of a tooth, and when the straight face 59 of the tooth is reached the arm 56 of the elbow lever will he suddenly released, permitting the weight of the drill to raise the pulley 53, and to make a sudden stroke in a downward direction.

The roller 53 is adapted to be engaged on its upper surface by a bracket 60 having a curved depression 61, fitting the face of the wheel and connected with a lever 62 pivoted as at 63 on the frame, the free end of the lever being adapted to engage a toothed quadrant 64 secured to the frame. By means of the lever and the bracket, the stroke of the drill may be stopped, and the pulley 53 locked in its lowermost position.

The reel 43 has winding thereon a rope 65 which passes over pulleys .66 and 67, journaled on the tripod at the front and rear thereof, the free end. of the rope being adapted to be attached to the slush bucket, or sound pump.

By connecting the parts of the clutch 48, 49 the reel 43 may be rotated to raise the bucket or pump out of the drill hole.
